Failure to build 9.0 -- matplotlib error

[Jeremy Martin]

I'm trying to build Sage 9.0 from source under MacOS Mojave 10.14.6. I ran into an error with matplotlib.  The end of the error message is below, and I'm attaching the logfile.

Error building Sage.

The following package(s) may have failed to build (not necessarily

during this run of 'make all-start'):

* package: matplotlib-2.2.4.p0

  log file: /Applications/sage-9.0/logs/pkgs/matplotlib-2.2.4.p0.log

  build directory: /Applications/sage-9.0/local/var/tmp/sage/build/matplotlib-2.2.4.p0

Any advice you can give will be helpful.  Thanks!

the interesting part of the log is

* The following required packages can not be built:
* png
* Try installing png with `brew install libpng` and
* pkg-config with `brew install pkg-config`

It seems you are building under Homebrew, but something goes wrong with libpng.
Do you have it installed?

Do you have Sage's libpng built?

Thanks, I did not notice that.  I will try it and report back.

Hmm.  I did "brew install libpng" and "brew install pkg-config", then tried to build again.  This time make threw an error that pkg-config was not installed.  Setting the PKG_CONFIG environment variable does not fix the problem.  I'm not sure what is going on, since pkg-config is located in /usr/local/bin, which is in both PKG_CONFIG and PATH.

The logfile is attached.  Thanks again for your help.

hmm, did you re-run ./configure after these installations?

could you post config.log ?

Same problem after running .configure and make.  Again, it breaks while trying to build brial.  New log attached.

Thanks again,

It seems like you have some old Sage bits in your PATH:

checking pkg-config is at least version 0.9.0...
/Applications/sage-8.4/local/bin/pkg-config

(and this results in an error, as this pkg-config has no idea about
Sage you want to build)

Make sure it's not found.
